Key Vaca, Fla., March 14, 1910; 7 <?, 1 9 . 

 Boot Key, Fla., March 14, 1910; 2 9 . 



We have before us all the available material of this species from 

 southern Florida and find that specimens from Cape Florida on Key 

 Biscayne, Long Key, Key Vaca and Boot Key, as a rule have the 

 body slightly more compressed, the face more retreating, and the 

 caudal femora slightly more slender. These differences from main- 

 land individuals are, however, very slight, not absolutely constant 

 and sometimes but one of the three may be appreciable, while a few 

 mainland specimens possess the usual insular characters. 



In size the Miami and Homestead individuals are but slightly 

 larger than Thomasville, Ga., specimens. The Boot Key and 

 Key Vaca representatives are much the same size as those from 

 Miami and Homestead, although several males are distinctly larger 

 than Thomasville individuals of the same sex. The Long Key 

 specimens exceed in size any individuals of the species seen by us, 

 the females particularly being very large. A series of five males 

 and six females from Cape Florida on Key Biscayne, average larger 

 than any series except that from Long Key. Measurements (in 

 millimeters) of average individuals from the localities mentioned 

 above are as follows: 



Thomas- 

 ville. Miami. 



Length of body 18.8 20.2 



Length of pronotum 4. 4.2 



Length of tegmen 16.8 16.2 



Length of caudal femur 13. 13.5

Length of body 24.5 29. 29.5 31. 31.8 29.5 



Length of pronotum 5.1 5.5 5.9 5.8 7. 6. 



Length of tegmen 20.5 21. 20.8 23.2 25. 22.2 



Length of caudal femur 16.5 18.5 17.5 20.2 21.8 19.2 



The usual polychromatism of the species is exemplified in the 

 present series. The Long Key females are all of the strongly bicolored 

 type with the dorsal aspect uniform ochraceous and the lateral and 

 ventral faces nearly uniform seal-brown. The males from the same 

 locality are similarly but much less decidedly colored, the same also 

 being true in the case of the Key Vaca individuals.
